Most vinegars are low FODMAP and safe to use freely in typical serving sizes. White vinegar, red wine vinegar, rice vinegar, and apple cider vinegar all fall comfortably in the low FODMAP range at normal culinary amounts. Balsamic vinegar is also low FODMAP but has a tighter serving limit because of its natural sugar content.
Plain Vinegars Are Low FODMAP
White vinegar, red wine vinegar, rice wine vinegar, and distilled vinegar contain virtually no fermentable sugars. The fermentation process that creates vinegar converts most of the original sugars into acetic acid, which isn’t a FODMAP. You can use these vinegars in salad dressings, marinades, and cooking without worrying about portion size in any realistic amount.
Apple Cider Vinegar Has a Generous Limit
Apple cider vinegar is low FODMAP at up to 2 tablespoons (30 ml) per meal. Since it’s made from apples, which contain the FODMAP sugar sorbitol, there is a threshold where it can cause symptoms. Monash University testing puts that threshold around 4 tablespoons (60 ml), which is when you start hitting sorbitol levels comparable to eating a whole apple. In practice, most people use 1 to 2 tablespoons at a time, which is well within the safe range.
If you like drinking diluted apple cider vinegar throughout the day, keep total intake to about 4 tablespoons spread across meals, with at least 3 hours between servings so FODMAPs don’t stack.
Balsamic Vinegar: Watch the Serving Size
Balsamic vinegar is low FODMAP at 1 tablespoon per sitting. It contains more residual sugars than other vinegars because it’s made from grape must that’s been reduced and aged, concentrating fructose. One tablespoon on a salad or drizzled over roasted vegetables is fine. Going significantly beyond that in a single meal could push you past the fructose cutoff.
The bigger concern is balsamic glazes and reductions sold in squeeze bottles at the grocery store. These are often not pure balsamic vinegar. Many contain added sweeteners like high fructose corn syrup, honey, or grape juice concentrate, all of which are high FODMAP. Always check the ingredients label. If the product lists anything other than balsamic vinegar (and possibly a small amount of thickener), treat it with caution.
Malt Vinegar Is Also Safe
Malt vinegar, made from barley, sometimes raises concerns because barley is a high FODMAP grain. But according to Monash University, products derived from wheat, rye, and barley (like malt vinegar, soy sauce, and wheat starch) are not high in fructans and are suitable on a low FODMAP diet. The fermentation and processing break down the fructan chains. Malt vinegar does contain trace gluten, so it’s not appropriate for celiac disease, but from a FODMAP standpoint it’s fine.
Quick Reference by Vinegar Type
- White, red wine, rice, and distilled vinegar: Low FODMAP at normal cooking and dressing amounts. No practical limit.
- Apple cider vinegar: Low FODMAP up to 2 tablespoons (30 ml) per meal.
- Balsamic vinegar: Low FODMAP at 1 tablespoon per sitting.
- Malt vinegar: Low FODMAP. Contains trace gluten but no significant fructans.
Flavored and Infused Vinegars
Plain vinegar is rarely the problem. Where people run into trouble is with flavored vinegars and vinegar-based products that contain added ingredients. Raspberry vinegar, fig-infused balsamic, and shrub syrups often include fruit juice, honey, or sugar that can push FODMAP content well above safe levels. The same goes for pre-made vinaigrettes that list garlic, onion, or honey in the ingredients.
Your safest approach during the elimination phase is to make your own dressings with plain vinegar, olive oil, salt, and FODMAP-friendly herbs. Once you move into the reintroduction phase, you’ll have a better sense of which specific sugars bother you and how much flexibility you have with flavored products.
